However, since the timer\nhandler rt5645_btn_check_callback() will re-queue the jack_detect_work,\nthis cleanup order is buggy.\n\nThat is, once the del_timer_sync in rt5645_i2c_remove is concurrently\nrun with the rt5645_btn_check_callback, the canceled jack_detect_work\nwill be rescheduled again, leading to possible use-after-free.\n\nThis patch fix the issue by placing the del_timer_sync function before\nthe cancel_delayed_work_sync.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8},"cwes":["CWE-416"],"references":["https://git.kernel.org/stable/c/061a6159cea583f1155f67d1915917a6b9282662","https://git.kernel.org/stable/c/0941150100173d4eaf3fe08ff4b16740e7c3026f","https://git.kernel.org/stable/c/1a5a3dfd9f172dcb115072f0aea5e27d3083c20e","https://git.kernel.org/stable/c/236d29c5857f02e0a53fdf15d3dce1536c4322ce","https://git.kernel.org/stable/c/2def44d3aec59e38d2701c568d65540783f90f2f"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:59:48.811064707+00:00"},"epss":{"cve":"CVE-2022-49493","score":0.00268,"percentile":0.19054,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
